Abstract

The currentless plasma with volume-averaged beta value of 2 % has been produced by neutral beam heating. It was initiated by the second harmonic resonance of the electron cyclotron waves (150 to 350 kW, and 53. 2 GHz). The beta value was increased by increasing the density of the target plasma with gas puffing during the neutral beam injection heating (23 to 30 keV, and 1. 3 to 2. 6 MW). Stable and unstable high-beta plasmas are observed. These plasmas were controlled by the neutral gas flow rate which was one of the key items to control the plasma pressure profile and plasma-wall interaction. The properties of the MHD activity and confinement on high-beta plasmas are discussed.
